With regards to wave functions

  1. Sep 30, 2011 #1
    If I draw a displacement-distance graph and a displacement-time for two wave forms, will both graphs look the same? With the exception of the x-axis label.

    yes i'm fairly sure they will be identical. Are the waves of the form x = asin(omega*t) ?

    They will be the same provided that...
    EITHER the waveform (shape of displacement against time graph) is sinusoidal,
    OR, for any waveform, the wave propagates without dispersion, which means that the wave speed is independent of waveform, i.e. independent of frequency for a sinusoid.
